How do you remove clutch on 139QMB without an impact?
This tool is safe to use it will not break the clutch cover?
How do i remove bigger 38mm nut that holds clutch together?
Whats the use of this tool advertised as clutch tool online, isn't it for crankshaft?

The clutch bell tool should be fine as long as you're not beating on it. What you'd be looking for is a "38mm axle nut socket" they call it at most auto parts stores. You'll still need a breaker bar and a way to hold the whole unit while you press down on the clutch (against the contra spring) while you loosen the 38mm nut. And brent ( 90GTVert) has tons... TONS! Of information on how to fix anything already sorted and categorized in the tech library. Here is the clutch removal without an impact. 49ccscoot.proboards.com/thread/527/removing-variator-cltuch-impact-wrench |

Okay thanks, however that socket on last photo its not for clutch right, its just they sell it in clutch toolkit on ebay that's why i am asking because it makes no sense in gy6 its used for crankshaft only AFAIK
Here's another impact alternative on 20th second of video

It probably is in your best interest to buy an impact tool. It may be true that that the variator and outer clutch nuts and the stator nut can be finessed loose with by other means but the impact tool will make your life soo much easier. I have a 12 vdc powered unit and love it. I tried to loosen the 38mm socket by other means but the impact tool got it loose with 2 or 3 whacks and no damage. You seem to have so many other things going on with your scooter(s) that you will get your investment out of an impact tool in short order.

Some time ago (2-3 years?) I got a black and decker matrix drill. Shortly after, i picked up the impact attachment for using on scooty stuff. It's no dewalt impact, and its definitely not strong enough to torque or remove well tightened lugnuts (might work on prius rims?) But it does amazing for scooty nut removals all around. I do use it -only- to snug the 38mm nut and rear tire nut. Before you get out your pitchforks, this is my own personal use with my own personal tools that i am extremely familiar with. I start every nut by hand all the way to bottom. THEN i use the impact to give the nuts a couple quick taps to snug it. The only reason I feel comfortable using my matrix impact to do that is that i can hold the big black 38mm impact socket still one handed. I dont know the exact torque output spec of it, but i very highly doubt it even comes close to 100 ft-lbs. Like i said, its no dewalt. I've used those big yellow 750 ft-lb beasts to remove axle nuts from lifted 1 ton pickups. Specific tools for specific jobs. So disclaimer - DO NOT use an impact to start, spin, or tighten nuts or bolts on a scooter. If you are new to mechanics and repair, if you have to question what to do, or you are at all unfamiliar with general or specific torque specs or what your tools are capable of, you shouldn't ever use an impact driver to assemble anything on a scooter. The metals used are in many cases softer or more delicate than full size automotives - and WILL strip or crossthread very easily. You have been disclaimed. |

The clutch nut is easy and I can do it on the road and, actually had to do so. Simply carry a strap wrench with you. Mine cost, I think, about $8. This will hold the bell from turning while your socket wrench turns the nut. I believe this nut should only be torqued to about 30 Ft. pounds so, once you do this with your torque wrench to put it back on...it will be a lot easier to remove. I also use blue locktite on the threads just in case. When I got my scoot and had to remove that nut the first time, it helped to hold the rear brake while turning the nut as the rear wheel wanted to turn with it. I guess someone before me put that nut on with an impact and it was waaaay too tight.

Greg Actually i went that way first got an cordless impact from walmart for $60 black and decker then i realized i need special (black) impact sockets for it and also need a bit that is 38 which will cost another $10.
Now after i read on other forum about using impact on weak Chinese steel might be an overkill and they recommend using hand tools even to loosen nuts otherwise chances of stripping the thread are high.
Well that makes sense since frame metal is soft other components might be as well, and after i use impact to remove the nut i still got to put it back on tight and even if i had torque wrench i would have to hold the components otherwise only option is to tighten by impact which is dangerous.
After doing all math i decided that if i need to still buy specialized locking tools i rather return the impact and impact bits back to the store and do everything by hand, safer and cost way less.

I have the kawasaki it has a 1/2" drive it came with two reversible sockets that fit the variator and the outer clutch nuts very well but I did have to buy the 38mm socket and it wasn't all that pricey. I have a difficult time with the idea that Chinese scoots will be damaged because of disassembly with an impact tool but won't debate that statement. But I will say phooey. And I wouldn't be without mine but it is your call.

I don't think youll be in trouble removing vari nuts;its when you put them ON with an impact you get in trouble.

I don't think youll be in trouble removing vari nuts;its when you put them ON with an impact you get in trouble. Exactly, I use my corded impact to remove both the variator and clutch nut when I happen to be at home, and put them both back on using socket wrench and then torque wrench with just a hint of blue locktite. My corded impact is rated at like 300 ft/pounds and would rip the threads clean off my crank without even trying. I will admit that sometimes, it is faster/easier for me to just use my socket wrench and locking tool and strap wrench than it is for me to dig out my extension cord and get it hooked up and run outside. Just remember those threads are cut into Chinesium and it is a good idea to treat them with a bit of care. Bill |
